I Have Been Locked Out of My Gmail/YouTube Account And Google Customer Service Is Not Providing Any Help!

Hi, I mainly use this account for YouTube. There is no emergency email nor phone number associated with the lost account. Furthermore, I have tried the "forgot password" option and provided the required answers best to my guess and even this did not help. Despite that I couldn't retrieve my last password accurately, I still remember 110% my previous password before it had been changed 9 months ago as notified by Google and yet this important piece of information is still not considered by Google and I keep getting the "unfortunately we couldn't verify your account” message!
I repeat, I know 110% my previous password before it was changed 9 months ago. Any help is highly appreciated. Thanks.

If phone number is associated with Gmail account you can easy to update your password otherwise its difficult to get back your gmail accont.

The typical process is not to retrieve a password, but to change it. That takes a system of verifications to reset the password. Can you reset the password as opposed to retrieving it?
